3、在项目中创建一个config的Source Folder，专门用于存放各种配置文件

1.记录日志 log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/2002/xmlspec/dtd/2.10/xmlspec.dtd">

</Configuration>`
  1. 在web.xml中配置核心过滤器和spring的监听器
<?xml version="1.0" encoding="UTF-8"?>

  </welcome-file-list>
  <!-- 监听器 -->

  </filter>
  <filter-mapping>
  	<filter-name>struts2</filter-name>
  	<url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>
  1. 添加struts.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <constant name="struts.devMode" value="true"></constant>
    
	<package name="ssh" namespace="/" extends="struts-default">
	<!-- 使用applicationContext2.xml中配置的action信息 
		如果不使用applicationContext2.xml中配置的action信息，就把applicationContext2.xml中配置的action信息
		删掉，class改成action的全路径类名
	-->
		<action name="userAction_*" class="userAction" method="{1}">
			<result name="add">/success.jsp</result>
			<!-- 版本的原因加上这句 -->
			<allowed-methods>add,update,del,find</allowed-methods>
		</action>
	</package>
</struts>
  1. applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

      <tx:advice id="txAdvice" transaction-manager="txManager">
      	<tx:attributes>
      		<!-- <tx:method>给切入点方法添加事务详情

      		read-only：是否只读-->
      		<tx:method name="save*" />
      		<tx:method name="update*" />
      		<tx:method name="delete*" />
      		<tx:method name="find*" />
      	</tx:attributes>
      </tx:advice>
      <!-- aop编写，让spring自动对目标生成代理，需要使用Aspectj的表达式 -->
       <aop:config>
      	<!-- 切入点 -->
      	<aop:pointcut expression="execution(* cn.itcast.service.*.* (..))" id="txPointCut"/>
      	<!-- 切面：将切入点与通知整合 -->
      	<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
      </aop:config>
</beans>

在上述配置中，首先配置了SessionFactory接口，并加载hibernate配置文件hibernate.cfg.xml，然后把SessionFactory配置到hibernate模板中，目的是使用sessionFactory接口提供的session类实例来操作po类，并使用hibernate模板进行数据库访问；接下来分别配置了dao、service和事务管理等信息。实际上，这样的配置就是将hibernate中用到的数据源、sessionFactory实例和事务管理器交予spring容器进行统一管理。

  1. hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
	"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

			</property>
			<!-- 用来关联hbm配置文件 -->
			<mapping resource="cn/itcast/domain/User.hbm.xml"/>
		</session-factory>
	</hibernate-configuration>

使用hibernate.cfg.xml文件

  1. Domain层
package cn.itcast.domain;

public class User {
	private Integer id;
	private String username;
	private String password;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", username=" + username + ", password=" + password + "]";
	}
	
}

User.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="cn.itcast.domain.User" table="t_user">
		<id name="id">
			<generator class="native"></generator>
		</id>
		<property name="username"></property>
		<property name="password"></property>
	</class>
</hibernate-mapping>

在hibernate.cfg.xml中添加<!-- 用来关联hbm配置文件 --> <mapping resource="cn/itcast/domain/User.hbm.xml"/>

  1. Dao层
package cn.itcast.dao;

import java.util.List;

import cn.itcast.domain.User;

public interface UserDao {
	public void save(User user);
	public void update(User user);
	public void delete(User user);
	public User findUserById(int id);
	public List<User> findAll();
}


package cn.itcast.dao.impl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.orm.hibernate5.HibernateTemplate;

import cn.itcast.dao.UserDao;
import cn.itcast.domain.User;

public class UserDaoImpl implements UserDao {
	private HibernateTemplate hibernateTemplate;
	
	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}

	@Override
	public void save(User user) {
		// TODO Auto-generated method stub
		this.hibernateTemplate.save(user);
	}

	@Override
	public void update(User user) {
		// TODO Auto-generated method stub
		this.hibernateTemplate.update(user);
	}

	@Override
	public void delete(User user) {
		// TODO Auto-generated method stub
		this.hibernateTemplate.delete(user);
	}

	@Override
	public User findUserById(int id) {
		// TODO Auto-generated method stub
		return this.hibernateTemplate.get(User.class, id);
	}

	@SuppressWarnings("unchecked")
	@Override
	public List<User> findAll() {
		// TODO Auto-generated method stub
		SessionFactory sessionFactory = this.hibernateTemplate.getSessionFactory();
		Session session = sessionFactory.getCurrentSession();
	//	Transaction transaction = session.beginTransaction();
		String hql = "from User";
		Query<User> query = session.createQuery(hql);
		List<User> list = query.list();
	//	transaction.commit();
	//	session.close();
	//	sessionFactory.close();
		return list;
	}

}
  1. Service层
package cn.itcast.service;

import java.util.List;

import cn.itcast.domain.User;

public interface UserService {
	public void save(User user);
	public void update(User user);
	public void delete(User user);
	public User findUserById(int id);
	public List<User> findAll();
}


package cn.itcast.service.impl;

import java.util.List;

import cn.itcast.dao.UserDao;
import cn.itcast.domain.User;
import cn.itcast.service.UserService;

public class UserServiceimpl implements UserService {
	private UserDao userDao;
	
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

	@Override
	public void save(User user) {
		// TODO Auto-generated method stub
		this.userDao.save(user);
	}

	@Override
	public void update(User user) {
		// TODO Auto-generated method stub
		this.userDao.update(user);
	}

	@Override
	public void delete(User user) {
		// TODO Auto-generated method stub
		this.userDao.delete(user);
	}

	@Override
	public User findUserById(int id) {
		// TODO Auto-generated method stub
		return this.userDao.findUserById(id);
	}

	@Override
	public List<User> findAll() {
		// TODO Auto-generated method stub
		return this.userDao.findAll();
	}

}

不使用hibernate.cfg.xml

  1. 使用HibernateDaoSupport
package cn.itcast.dao.impl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

import cn.itcast.dao.UserDao;
import cn.itcast.domain.User;
/*
 *不使用hibernate.cfg.xml
 *继承HibernateDaoSupport自动生成模板，必须提供sessionFactory
 */
public class UserDaoImpl2 extends HibernateDaoSupport implements UserDao {

	@Override
	public void save(User user) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().save(user);
	}

	@Override
	public void update(User user) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().update(user);
	}

	@Override
	public void delete(User user) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().delete(user);
	}

	@Override
	public User findUserById(int id) {
		// TODO Auto-generated method stub
		return this.getHibernateTemplate().get(User.class, id);
	}

	@SuppressWarnings("unchecked")
	@Override
	public List<User> findAll() {
		// TODO Auto-generated method stub
		SessionFactory sessionFactory = this.getHibernateTemplate().getSessionFactory();
		Session session = sessionFactory.openSession();
		String hql = "from User";
		Query<User> query = session.createQuery(hql);
		List<User> list = query.list();
		return list;
	}
	

}
  1. 创建c3p0-db.properties
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/数据库名
jdbc.user=root
jdbc.password=密码

3.修改配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

      	<property name="userService" ref="userService"></property>
      </bean>
      
</beans>

Action创建交予Spring

  1. 创建action类
package cn.itcast.action;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

import cn.itcast.domain.User;
import cn.itcast.service.UserService;

public class UserAction extends ActionSupport implements ModelDriven<User>{

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private User user = new User();
	
	@Override
	public User getModel() {
		// TODO Auto-generated method stub
		return this.user;
	}
	
	private UserService userService;

	public void setUserService(UserService userService) {
		this.userService = userService;
	}
	public String add() {
		this.userService.save(user);
		return "add";
	}
	

}

2.修改applicationContext.xml ，添加如下代码

<!-- 配置action -->
      <bean id="userAction" class="cn.itcast.action.UserAction" scope="prototype">
      	<property name="userService" ref="userService"></property>
      </bean>

3.struts.xml配置见上

4.测试
index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>登录</title>
</head>
<body>
<div align="center" >
	<form action="${pageContext.request.contextPath }/userAction_add" method="post">
		用户名：<input type="text" name="username"/><br/>
		密码：<input type="password" name="password"/><br/>
		<input type="submit" value="登录">
	</form>
</div>
</body>
</html>

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
添加成功
</body>
</html>

Struts2自身创建Action

删除applicationContext.xml中对action的配置代码，同时修改Struts配置文件struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <constant name="struts.devMode" value="true"></constant>
    
	<package name="ssh" namespace="/" extends="struts-default">
	<!-- 使用applicationContext2.xml中配置的action信息 
		如果不使用applicationContext2.xml中配置的action信息，就把applicationContext2.xml中配置的action信息
		删掉，class改成action的全路径类名
	-->
		<action name="userAction_*" class="**action的全路径类名**" method="{1}">
			<result name="add">/success.jsp</result>
			<!-- 版本的原因加上这句 -->
			<allowed-methods>add,update,del,find</allowed-methods>
		</action>
	</package>
</struts>
